As I outlined in January, industrial bellwether Alcoa (AA) is starting to signal better quarters ahead for the U.S. economy. Alcoa's sales will likely increase 10% to 13% in 2011, after a 14% surge in 2010, the latter albeit against an easy comparison.

Further, U.S. auto sales are likely to rise 10% to 13% this year, and the housing sector could squeeze out a modest uptrend in new home sales, if a better second-half performance materializes, as expected. This is all good news for aluminum sales and AA. Another positive: The price of aluminum should rise in 2011 on adequate global demand and falling inventories.

Alcoa (AA) is the world leader in the production and management of primary aluminum, fabricated aluminum and alumina. The company has a significant presence in all segments of the aluminum industry and operates in more than 31 countries worldwide. The company competes with other international metals and mining giants like Rusal, Rio Tinto (RTP), BHP Billiton (BHP) and Chalco (ACH).

The company recently released its Q4 2010 earnings, and we have updated our price estimate to $17.68 based on a reduction in total debt, an increase in revenues from better product pricing and better cash management leading to cost savings.

Primary Metals the Biggest Driver of Value

The primary metals division produces primary aluminum used by Alcoa's fabricating businesses, and it is sold to external customers, aluminum traders and on commodity markets. While our analysis shows that it was Alcoa's most valuable division in terms of contributor to shareholder's income, we have further increased our estimates for the overall value of the division going forward.

Aluminum prices have increased over the last two years since their sudden decline from peak prices in mid-2008. The 13% increase in global aluminum prices in 2010 has been directly responsible for the observed increase in the division's revenue.

We capture the impact of the aluminum prices on Alcoa's revenues in our forecast for the yearly average price of primary metals.

With demand for aluminum predicted to increase from 10-15% in developing countries like China, South Korea, Thailand and India, Alcoa's estimate of a 12% growth rate for 2011 is well justified. We believe that the demand growth will increase Alcoa's revenue per ton of aluminum sold to as high as $3,400 in coming years from its current value of about $2,500.

Industrial bellwether Alcoa is starting to signal "better quarters ahead" for the U.S. economy. Alcoa beat the fourth quarter Thomson Reuters First Call earnings estimate by 2 cents, earning 21 cents, and if the company's sales increase trend continues, look for a 10% to 13% revenue gain in 2011, after a 12% to 14% surge in 2010.

Alcoa

Analysts forecast that earnings for the period will come to 19 cents per share, up from just a penny per share in the same quarter of last year. The New York-based aluminum producer also is expected to post revenue of $5.7 billion for the three months that ended in December, which is 4.5% more than a year earlier.

Alcoa (AA - option chain) stock is trading lower with other aluminum stocks this morning on reports that premiums for aluminum shipments to Japan will likely fall during the first quarter of 2011. A report stated that analysts believe aluminum premiums are already in a downtrend and could dip as much as 10%. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on AA.

This morning, AA opened at $13.10. So far today the stock has hit a high of $13.14 and a low of $12.96. As of 12:30, AA is trading at $12.99, down $0.30 (-2.3%). The chart for AA looks bullish and S&P gives AA a positive 4 STARS (out of 5) buy ranking.

The earnings season kicked off last week with better-than-expected results from Alcoa (AA) and Yum! Brands (YUM), while Marriott (MAR) and Pepsico (PEP) met consensus EPS estimates. This week, bellwether companies Intel (INTC), General Electric (GE), Google (GOOG) and JPMorgan Chase (JPM) are scheduled to report their third-quarter results, and analysts polled by Thomson Reuters are looking for earnings growth from all of them.

Santa Clara, Calif.-based Intel announced the acquisition of McAfee and joint ventures with General Electric and Nokia (NOK) during its third quarter. Analysts forecast earnings for that period to come to 50 cents per share, which is up 34.0% from the same period of last year. The number one semiconductor maker's revenue for the three months ended in September is expected to total $11.0 billion, or 17.1% more than a year earlier. Looking ahead to the full year, the forecast thus far is for earnings of $1.94 per share (+44.8%) and $43.3 billion in revenue (+23.4%). The per-share earnings topped analysts' expectations in the past four quarters, by as much as a dime per share.

I last discussed aluminum company Alcoa (AA) back in July. At that time, its price was roughly around the $11 mark. Thursday, the stock closed the regular session at $12.20. During the extended-hours trading that followed, the stock rose 2.8% to $12.54 in reaction to the release of the third-quarter report. The 52-week low for the shares is $9.81, so they're comfortably above that level. It's time for long-term investors and short-term participants to decide how the stock looks now that the numbers are out.

Let's first go to the one-year chart. Such a graphic doesn't make things easy, does it? The overall pullback makes the stock appear weak, but I nevertheless see an equity that wants to clear some more resistance levels if only the rest of the market will help it out.

Alcoa (AA), Marriott (MAR) and Yum! Brands (YUM) kick off the new earnings season this week. Analysts surveyed by Thomson Reuters are looking for moderate year-over-year earnings and revenue growth in the third quarter from each of these dividend payers.

Note that Marriott and Yum! Brands have exceeded consensus estimates in recent quarters and have First Call consensus buy recommendations as well. They are also trading near their 52-week highs, while Alcoa shares are closer to the 52-week low despite a 22% rise in the past three months.
